SEMINAR ANNOUNCEMENT

Wednesday January 20 2016, at 2.30 p.m.

FABIO TANTURRI (Aix-Marseille Université)
will speak on

Matrix factorizations and curves in P^4

Abstract: A method to prove the unirationality of 
a moduli space of curves or of
other interesting spaces is to explicitly exhibit a unirational dominating
family of projective models. In this talk, I will show how it is possible to
construct curves in P^4 by means of matrix factorizations; by using this
new technique, we are able to prove the unirationality of the Hurwitz
space H_8,12, as well as other results concerning particular Brill-Noether
spaces. This is a joint work with Frank-Olaf Schreyer.


Venue: Seminar Room  (Sezione di Matematica e 
Informatica, H2 building, Via Valerio 12/1, 3rd 
floor, room 334)

Everybody interested is much welcome to attend.
